摘要：

Fluorescence lifetime tau and fluorescence quantum yield PHI(F) of thiophene oligomers with two to six rings were measured in solution. Radiative and nonradiative constants were estimated. The tau and PHI(F) values increased with ring number, n, mainly caused by a decrease of nonradiative decay.
